  • PHP: Formatting multi-dimensional array as HTML?

    - by Industrial
    Hi everybody, I have tried to get my head around building a recursive function to handle formatting of a unknown depth multi-dimensional array to HTML and nested Divs. I thought that it should be a piece of cake, but no. Here's what I have come up with this far: function formatHtml($array) { $var = '<div>'; foreach ($array as $k => $v) { if (is_array($v['children']) && !empty($v['children'])) { formatHtml($v['children']); } else { $var .= $v['cid']; } } $var.= '</div>'; return $var; } And here's my array: Array ( [1] => Array ( [cid] => 1 [_parent] => [id] => 1 [name] => 'Root category' [children] => Array ( [2] => Array ( [cid] => 2 [_parent] => 1 [id] => 3 [name] => 'Child category' [children] => Array () ) ) ) ) Thanks a lot!

  • PHP Array - some further problems with displaying elements in the array

    - by Homer_J
    Hi again, Thanks in advance for the help. Here is my array based on $rowq: Array ( [0] => Array ( [questions] => q8 [qnum] => 8 [qtext] => I know how what I do fits into my team's objectives [page] => 1 ) [1] => Array ( [questions] => q8 [qnum] => 8 [qtext] => I know how what I do fits into my team's objectives [page] => 1 ) [2] => Array ( [questions] => q8 [qnum] => 8 [qtext] => I know how what I do fits into my team's objectives [page] => 1 ) [3] => Array ( [questions] => q8 [qnum] => 8 [qtext] => I know how what I do fits into my team's objectives [page] => 1 ) [4] => Array ( [questions] => q8 [qnum] => 8 [qtext] => I know how what I do fits into my team's objectives [page] => 1 ) [5] => Array ( [questions] => q8 [qnum] => 8 [qtext] => I know how what I do fits into my team's objectives [page] => 1 ) [6] => Array ( [questions] => q8 [qnum] => 8 [qtext] => I know how what I do fits into my team's objectives [page] => 1 ) [7] => Array ( [questions] => q8 [qnum] => 8 [qtext] => I know how what I do fits into my team's objectives [page] => 1 ) ) I would like to display elements of the array using (i think) the foreach statement but I can't get it working, ideally, I would like to echo something like this echo "<tr>".$rowq[qnum]." is the questions number and the question text is ".$rowq[qtext].". The page and q values are ".$rowq[page]." and ".$rowq[questions]." respectively."; And that link of text would appear how however many rows the array has in it. Any and all advice appreciated - I'm struggling like heck to get my head around multi-dimensional arrays :( Homer.

  • Safe way for getting/finding a vertex in a graph with custom properties -> good programming practice

    - by Shadow
    Hi, I am writing a Graph-class using boost-graph-library. I use custom vertex and edge properties and a map to store/find the vertices/edges for a given property. I'm satisfied with how it works, so far. However, I have a small problem, where I'm not sure how to solve it "nicely". The class provides a method Vertex getVertex(Vertexproperties v_prop) and a method bool hasVertex(Vertexproperties v_prop) The question now is, would you judge this as good programming practice in C++? My opinion is, that I have first to check if something is available before I can get it. So, before getting a vertex with a desired property, one has to check if hasVertex() would return true for those properties. However, I would like to make getVertex() a bit more robust. ATM it will segfault when one would directly call getVertex() without prior checking if the graph has a corresponding vertex. A first idea was to return a NULL-pointer or a pointer that points past the last stored vertex. For the latter, I haven't found out how to do this. But even with this "robust" version, one would have to check for correctness after getting a vertex or one would also run into a SegFault when dereferencing that vertex-pointer for example. Therefore I am wondering if it is "ok" to let getVertex() SegFault if one does not check for availability beforehand?

  • 3d vertex translated onto 2d viewport

    - by Dan Leidal
    I have a spherical world defined by simple trigonometric functions to create triangles that are relatively similar in size and shape throughout. What I want to be able to do is use mouse input to target a range of vertices in the area around the mouse click in order to manipulate these vertices in real time. I read a post on this forum regarding translating 3d world coordinates into the 2d viewport.. it recommended that you should multiply the world vector coordinates by the viewport and then the projection, but they didn't include any code examples, and suffice to say i couldn't get any good results. Further information.. I am using a lookat method for the viewport. Does this cause a problem, and if so is there a solution? If this isn't the problem, does anyone have a simple code example illustrating translating one vertex in a 3d world into a 2d viewspace? I am using XNA.

  • OpenGL Vertex Attributes - Normalisation

    - by Daniel
    Alas, I have searched, and have found no definitive answer. When would you normalize the vertex data in OpenGL using the following command: glVertexAttribPointer(index, size, type, normalize, stride, pointer); I.e when would normalize == GL_TRUE; what situations, and why would you choose to let the GPU do the calculations instead of preprocessing it? All examples I have ever seen, have this set to GL_FALSE; and I cannot personally see a use for it. But Khronos aren't stupid, so it must be there for something useful (and probably common).

  • Y Axis inverted on vertex output

    - by Yonathan Klijnsma
    I've got my project running and somehow it seems my vertex y components are inverted. 10 in the positive on Y goes down and 10 negative on the Y axis goes up. I can't find anything with the initialization and I am not doing any negative scaling in the view matrix. I've never had something like this happen before, does anyone have some tips or things to look for ? How I am sending verteces to the GPU ( Currently intermediate mode ) glVertex3f( x_pos_n, 10, z_pos ); I am using CG in the project but even without shaders the Y axis seems to be inverted.

  • Sort a set of multidimensional arrays by array elements

    - by Joseph Carrington
    Let's say I've started here: $arr[0] = array('a' => 'a', 'int' => 10); $arr[1] = array('a' => 'foo', 'int' => 5); $arr[1] = array('a' => 'bar', 'int' => 12); And I want to get here: $arr[0] = array('a' => 'foo', 'int' => 5); $arr[1] = array('a' => 'a', 'int' => 10); $arr[1] = array('a' => 'bar', 'int' => 12); How can I sort the elements in an array by those elements elements? Multidimensional arrays always feel like a little bit more than my brain can handle (-_-) (until I figure them out and they seem super easy)

  • Get the top nth values from a rectangular array

    - by user355925
    I am reading a txt file for strings that represent integers. The file is space delimited. I have created an array[10,2]. Everytime the strings 1~10 is found in the file I increment array[n,0] by 1. I also feed array[n,1] with numbers 1~10. i.e. txt file contents: 1/1/1 10/1/2001 1 1 10 2 2 3 1 5 10 word word 3 3 etc.. streamreader reads 1/1/1 and determines that is is not 1~10 streamreader reads 10/1/2001 and determines that it is not 1~10 streamreader reads 1 and ++array[0,0] streamreader reads 1 and ++array[0,0] streamreader reads 10 and ++array[9,0] etc.. The result will be: '1' was found 3 times '2' was found 2 times '3' was found 3 times '5' was found 1 time '10' was found 2 times My problem is that I need this array placed in order(sorted) by value of column 0 so that it would be: 1 3 2 10 5

  • Sun Grid Engine (SGE) / limiting simultaneous array job sub-tasks

    - by wfaulk
    I am installing a Sun Grid Engine environment and I have a scheduler limit that I can't quite figure out how to implement. My users will create array jobs that have hundreds of sub-tasks. I would like to be able to limit those jobs to only running a set number of tasks at the same time, independent of other jobs. Like I might have one array job that I want to run 20 tasks at a time, and another I want to run 50 tasks at a time, and yet another that I'm fine running without limit. It seems like this ought to be doable, but I can't figure it out. There's a max_aj_instances configuration option, but that appears to apply globally to all array jobs. I can't see any way to use consumable resources, as I'd need a "complex attribute" that is per-job, and that feature doesn't seem to exist. It didn't look like resource quotas would work, but now I'm not so sure of that. It says "A resource quota set defines a maximum resource quota for a particular job request", but it's unclear if an array job's sub-tasks' resource requests will be aggregated for the purposes of the resource quota. I'm going to play with this, but hopefully someone already knows outright.

    hy, i have a little, big problem here :) after i upload some images i get a list with all the images. I have some jQuery function for rotate, duplicate, delete, shuffle images! when i select a image and hit delete i send a post to php with the alt="" value of the image,i identify the picture and edit. I want to make a save button, Instead of sending a post every time i rotate a image, better send a post after editing the list of images with an array that contains all data? my php array after upload looks like this: [files] => Array ( [lcxkijgr] => lcxkijgr.jpg [xcewxpfv] => xcewxpfv.jpg [rtiurwxf] => rtiurwxf.jpg [gsbxdsdc] => gsbxdsdc.jpg ) say that I uploaded 4 pictures, firs picture i rotate 90 degrees second i want to duplicate third i rotate 270 degrees and the fourth image i delete i can do all this only with jQuery, but on the server the images are the same, after a refresh the images are the same this is the list with the images: <div class="upimage"> <ul id="upimagesQueue"> <li id="upimagesHPVEJM"> <a href="javascript:jQuery('#upimagesHPVEJM').showlargeimage('HPVEJM')"> <img alt="lcxkijgr" src="uploads/s6id9r9icnp8q9102h8md9kfd7/lcxkijgr.jpg?1272087830477" id="HPVEJM" style="display: block;" > </a> </li> <li id="upimagesSTCSAV"> <a href="javascript:jQuery('#upimagesSTCSAV').showlargeimage('STCSAV')"> <img alt="xcewxpfv" src="uploads/s6id9r9icnp8q9102h8md9kfd7/xcewxpfv.jpg?1272087831360" id="STCSAV" style="display: block;" > </a> </li> <li id="upimagesBFPUEQ"> <a href="javascript:jQuery('#upimagesBFPUEQ').showlargeimage('BFPUEQ')"> <img alt="rtiurwxf" src="uploads/s6id9r9icnp8q9102h8md9kfd7/rtiurwxf.jpg?1272087832162" id="BFPUEQ" style="display: block;" > </a> </li> <li id="upimagesRKXNSV"> <a href="javascript:jQuery('#upimagesRKXNSV').showlargeimage('RKXNSV')"> <img alt="gsbxdsdc" src="uploads/s6id9r9icnp8q9102h8md9kfd7/gsbxdsdc.jpg?1272087832957" id="RKXNSV" style="display: block;"> </a> </li> <ul> </div> is ok if i make one array like this: array{ imgFromLi = array(img1,img2,img3,img4,img5,img6) rotate = array{img1=90, img2=270, img3=90} delete = array{img4,img5,img6} duplicate = array{img2, img3} } how i can send/cache this array?? sorry for my very bad english

  • Peek ahead when iterating an array in PHP 5.2

    - by pako
    Is it possible to "peek ahead" while iterating an array in PHP 5.2? For example, I often use foreach to manipulate data from an array: foreach($array as $object) { // do something } But I often need to peek at the next element while going through the array. I know I could use a for loop and reference the next item by it's index ($array[$i+1]), but it wouldn't work for associative arrays. Is there any elegant solution for my problem, perhaps involving SPL?

  • C# Array or Dictionary?

    - by Valentin
    Hi. I wanted to know is C# array has a constant access speed? I need to store 1000 items in static array, that will be initialized during server startup. This array will be used readonly, so there will be no changes to array. Should I use a simple C# array (new MyClass[]) or Dictionary instead. I am really new to C# and trying to understand how C# arrays access works. Can they be compared to c++ arrays by speed?

  • How do I generate an Array string from an array in memory (php).

    - by Itay Moav
    I need to create a big array in my code, I have the values in several tables (for easy management). I select it and now I have all the values in an array, in memory in the way I want. My problem, I need to write this array down, into the code. Is there a way to take an array which sits in the memory and translate it into a string "array('g'='h','b'='d'....)" which I can then echo and just copy-paste into my code?

  • Generating Deep Arrays: Shallow to Deep, Deep to Shallow or Bad idea?

    - by MobyD
    I'm working on an array structure that will be used as the data source for a report template in a web app. The data comes from relatively complex SQL queries that return one or many rows as one dimensional associative arrays. In the case of many, they are turned into two dimensional indexed array. The data is complex and in some cases there is a lot of it. To save trips to the database (which are extremely expensive in this scenario) I'm attempting to get all of the basic arrays (1 and 2 dimension raw database data) and put them, conditionally, into a single, five level deep array. Organizing the data in PHP seems like a better idea than by using where statements in the SQL. Array Structure Array of years( year => array of types( types => array of information( total => value, table => array of data( index => db array ) ) ) ) My first question is, is this a bad idea. Are arrays like this appropriate for this situation? If this would work, how should I go about populating it? My initial thought was shallow to deep, but the more I work on this, the more I realize that it'd be very difficult to abstract out the conditionals that determine where each item goes in the array. So it seems that starting from the most deeply nested data may be the approach I should take. If this is array abuse, what alternatives exist?

  • How can I calculate a vertex normal for a hard edge?

    - by K.G.
    Here is a picture of a lovely polygon: Circled is a vertex, and numbered are its adjacent faces. I have calculated the normals of those faces as such (not yet normalized, 0-indexed): Vertex 1 normal 0: 0.000000 0.000000 -0.250000 Vertex 1 normal 1: 0.000000 0.000000 -0.250000 Vertex 1 normal 2: -0.250000 0.000000 0.000000 Vertex 1 normal 3: -0.250000 0.000000 0.000000 Vertex 1 normal 4: 0.250000 0.000000 0.000000 What I'm wondering is, how can I determine, taken as given that I want this vertex to represent a hard edge, whether its normal should be the normal of 1/2 or 3/4? My plan after I glanced at the sketch I used to put this together was "Ha! I'll just use whichever two faces have the same normal!" and now I see that there are two sets of two faces for which this is true. Is there a rule I can apply based on the face winding, angle of the adjacent edges, moon phase, coin flip, to consistently choose a normal direction for this box? For the record, all of the other polygons I plan to use will have their normals dictated in Maya, but after encountering this problem, it made me really curious.

  • Octrees and Vertex Buffer Objects

    - by sharethis
    As many others I want to code a game with a voxel based terrain. The data is represented by voxels which are rendered using triangles. I head of two different approaches and want to combine them. First, I could once divide the space in chunks of a fixed size like many games do. What I could do now is to generate a polygon shape for each chunk and store that in a vertex buffer object (vbo). Each time a voxel changes, the polygon and vbo of its chunk is recreated. Additionally it is easy to dynamically load and reload parts of the terrain. Another approach would be to use octrees and divide the space in eight cubes which are divided again and again. So I could efficiently render the terrain because I don't have to go deeper in a solid cube and can draw that as a single one (with a repeated texture). What I like to use for my game is an octree datastructure. But I can't imagine how to use vbos with that. How is that done, or is this impossible?

  • Selecting a multi-dimensional array in LINQ

    - by mckhendry
    I have a task where I need to translate a DataTable to a two-dimensional array. That's easy enough to do by just looping over the rows and columns (see example below). private static string[,] ToArray(DataTable table) { var array = new string[table.Rows.Count,table.Columns.Count]; for (int i = 0; i < table.Rows.Count; ++i) for (int j = 0; j < table.Columns.Count; ++j) array[i, j] = table.Rows[i][j].ToString(); return array; } What I'd really like to do is use a select statement in LINQ to generate that 2D array. Unfortunately it looks like there is no way in LINQ to select a multidimensional array. Yes, I'm aware that I can use LINQ to select a jagged array, but that's not what I want. Is my assumption correct, or is there a way to use LINQ to select a multi-dimensional array?

  • Convert a nested array into a flat array with PHP

I'm kinda struggling with this for a while now and figures, maybe some users at SO can help me out here. I've tried multiple things with recursion, all without luck so far... Any help is much appriciated! Thanks in advance, Ben Fransen
